HEATING-RADIATOR;

To all 'whom t may concern Be it known that lwe, `ALBERT El BAUM andAUGUST Scl-1on1., both citizens of the United States, and residents ofVaterloo, in the county of Blackhawk and State of Iowa, have invented anew and llmproved `Heating-Radiator, of which `the following'isa full,clear, and exact description.

Among the principal objects which the present invention has `ini vieware: to provide a heater adapted for installation in the usual fireopeningof a chimney-breast, employing water as a storage me ium; and toprovide a boiler for a heater of the character mentioned, simple andi`economical in iconstruction. and adapted to provide free and easycirculation of heated air.;

Reference is to be had tothe accompanying drawings forming` apart ofthis specificationz in which similar characters of referenceindicatecorresponding parts `in all the views, andin which-- Figure 1 isavertical cross section `of a chimney structure, showing as appliedthereto a radiator constructed and arranged in accordance with thepresent invention; Fig.;

2 is a front view of the same, partly cut away at one side to show thecirculating passages provided inwthe construction; and Fig. is ahorizontal section taken on the line 3--8 in Fig.,1.`

As seen in the accompanying drawings,

the heater comprises a fire-box or pot 8,hav ing grate bars 9 and anash-pan 10,`all of any desired and usual construction.

Where desired, it` will be understood that any suitable form of` gas`fuel heater may be employed as a substitute for the heater herein shown,wherein the` form of fuel is preferably small-sized coal.

The box 8 is Iinpart fcrmedby a :platemetal back 11, sides of thesamematerial, a

door 12, and a tube-plate118.` .The back 11 and sides thereof, togetherwith the tube `plate 13, formlthe major portion of the bottom structureof a boiler 14:. a The boiler 14:

is provided with aseries of hot-air tubes 15, which are verticallydisposed,and pass through a tube plate 16, which forms the top of theboiler 14h A back `plate 17, front plate 18 and outer side plates 19constitute the remainder of the structure of the boiler.

As shown best in Fig. Bof drawings, the backplate 17 and the side plates19, inconjunction withthe back :11, and sides 20 of the fire-box, form alwater-containing 1pas- Specicaton orLetters Patent. i Patented Apr.` 1

The communication between the passages 21 and the iue 26 isdisposed adjacent the lower end of said flue 26, the side walls to theflue A of the chimneystructure Bil to the passage 22, and thence, way ofthe the openair through the iiue A of the chimbox as a `water jacket. Inthis manner prowater in the boiler 14. the water in the boiler 14 isprovided by means of inlet pipes 28 and outlet pipes 29.

It will be understood that any safety `deter may be provided.
